void PINS_DRV_ClearPins | ( | GPIO_Type *const | base, |
pins_channel_type_t | pins | ||
) |
Write pins to 'Clear' value.
This function configures output pins listed in parameter pins (bits that are '1') to have a 'cleared' value (LOW). Pins corresponding to '0' will be unaffected.
base | GPIO base pointer (PTA, PTB, PTC, etc.) |
pins | pin mask of bits to be cleared. Each bit represents one pin (LSB is pin 0, MSB is pin 31). For each bit:

pins_channel_type_t PINS_DRV_GetPinsOutput | ( | const GPIO_Type *const | base | ) |
Get the current output from a port.
This function returns the current output that is written to a port. Only pins that are configured as output will have meaningful values.
base | GPIO base pointer (PTA, PTB, PTC, etc.) |
Definition at line 283 of file pins_driver.c.
status_t PINS_DRV_Init | ( | uint32_t | pinCount, |
const pin_settings_config_t | config[] | ||
) |
Initializes the pins with the given configuration structure.
This function configures the pins with the options provided in the provided structure.
[in] | pinCount | the number of configured pins in structure |
[in] | config | the configuration structure |
Definition at line 53 of file pins_driver.c.
pins_channel_type_t PINS_DRV_ReadPins | ( | const GPIO_Type *const | base | ) |
Read input pins.
This function returns the current input values from a port. Only pins configured as input will have meaningful values.
base | GPIO base pointer (PTA, PTB, PTC, etc.) |
Definition at line 340 of file pins_driver.c.
void PINS_DRV_SetPins | ( | GPIO_Type *const | base, |
pins_channel_type_t | pins | ||
) |
Write pins with 'Set' value.
This function configures output pins listed in parameter pins (bits that are '1') to have a value of 'set' (HIGH). Pins corresponding to '0' will be unaffected.
base | GPIO base pointer (PTA, PTB, PTC, etc.) |
pins | pin mask of bits to be set. Each bit represents one pin (LSB is pin 0, MSB is pin 31). For each bit:

void PINS_DRV_TogglePins | ( | GPIO_Type *const | base, |
pins_channel_type_t | pins | ||
) |
Toggle pins value.
This function toggles output pins listed in parameter pins (bits that are '1'). Pins corresponding to '0' will be unaffected.
base | GPIO base pointer (PTA, PTB, PTC, etc.) |
pins | pin mask of bits to be toggled. Each bit represents one pin (LSB is pin 0, MSB is pin 31). For each bit:

void PINS_DRV_WritePin | ( | GPIO_Type *const | base, |
pins_channel_type_t | pin, | ||
pins_level_type_t | value | ||
) |
Write a pin of a port with a given value.
This function writes the given pin from a port, with the given value ('0' represents LOW, '1' represents HIGH).
base | GPIO base pointer (PTA, PTB, PTC, etc.) |
pin | pin number to be written |
value | pin value to be written
|

void PINS_DRV_WritePins | ( | GPIO_Type *const | base, |
pins_channel_type_t | pins | ||
) |
Write all pins of a port.
This function writes all pins configured as output with the values given in the parameter pins. '0' represents LOW, '1' represents HIGH.
base | GPIO base pointer (PTA, PTB, PTC, etc.) |
pins | pin mask to be written
